Solid-state fermentation of hemp waste: enhancing the performance of Hermetia illucens larvae and altering the composition of hemp secondary metabolites

mycolabadmin

Researchers tested whether fermenting hemp plant waste with different mushroom types could make it a better food source for black soldier fly larvae, which produce valuable protein for animal feed. They found that different mushroom species had different effects: Ganoderma lucidum significantly increased the amount of larvae produced, while Trichoderma reesei increased beneficial cannabinoid content. Pleurotus ostreatus and Hypsizygus ulmarius removed unwanted cannabinoids from the waste. This approach offers a promising way to turn hemp waste into high-quality insect feed while controlling the levels of bioactive compounds.

Synergistic inhibition of Aspergillus flavus by organic acid salts: growth, oxidative stress, and aflatoxin gene modulation

mycolabadmin

A dangerous fungus called Aspergillus flavus contaminates animal feed and produces harmful toxins called aflatoxins that can make animals sick. Researchers tested a combination of three salt-based organic acids commonly used as natural food preservatives and found they work together to kill this fungus much better than using them individually. The combination damages the fungus’s cell structure, creates harmful reactive oxygen inside the cells, and shuts down the genes that produce the toxins, making it an excellent safe option for protecting animal feed.

Negative Effects of Occurrence of Mycotoxins in Animal Feed and Biological Methods of Their Detoxification: A Review

mycolabadmin

Molds that grow on grains and feed produce toxic substances called mycotoxins that can seriously harm farm animals, causing liver and kidney damage, reproductive problems, and reduced productivity. While proper storage and farming practices help prevent contamination, some mycotoxins still get through. Recent research shows that beneficial bacteria like those in yogurt and certain yeasts can effectively remove these toxins from animal feed, making it safer for livestock while protecting the environment from harmful chemicals.

Identification of an antifungal lipopeptide from Bacillus amyloliquefaciens HAU3 inhibiting the growth of Fusarium graminearum using preparative chromatography and 2D-NMR

mycolabadmin

Scientists discovered a beneficial soil bacterium called Bacillus amyloliquefaciens that produces a natural antifungal compound called fengycin, which effectively kills dangerous mold (Fusarium graminearum) that contaminates animal feed. This bacterium can be used as a biological control agent to prevent fungal growth and reduce harmful mycotoxins in livestock feed, offering a safer and more environmentally friendly alternative to chemical fungicides. The study shows the bacterium’s compounds damage fungal cell membranes and generate harmful stress molecules that kill the fungus.
